`(1^(th))/(5)` of a rod was painted black.`(2^(rd))/(3)` part of the total rod was coloured white.The part of the rod left without colour was

What is the function of rod cells on the retina? Which cells detect colours?

(1)/(10) of a pole is coloured white,(1)/(20) is coloured red,(1)/(30) is coloured green and the rest is coloured black.If the length of the black portion is 14m 70cm,then find the length of the pole.

A uniform rod of length 2a is placed horizontally on the edge of a table. Initially the centre of mass of the rod is at a distance a//3 from the edge. The rod is released from rest. If the rod slips after it turned an angle theta , find the coefficient of friction between the rod and the table.

The ends of a rod of length l move on the co- ordinate axes.The lecus of the point on the rod which divides it in the ratio 1:2 is

An 85 m long rod is divided into two parts. if one part is (2)/(3) of the other part, then the shorter part (in metres) is:

Two equal and opposite point forces applied at mid- points of the ends of a rod of square cross shown. Consider the dotted section ABCD . If the rod is cut across this Gloss section, the force exerted by the right part of the rod on left part across this cross section is

In a mobileshop 7/12 mobiles are imported and rest are manufactured in India. Further 1/5 th Indian mobiles are coloured while 5/7 th imported mobile are black and white. If there are total 150 coloured mobile in his shop, then total number of mobile phones in his shop is :

A vertical rod is partially submerged in an aquarium. You look at the aquarium from some distance. Does the underwater part of the rod appear to be closer than, farther than or the same distance as the top of the rod.

A metal rod of cross sectional area 1.0cm^(2) is being heated at one end. At one time , the temperature gradient is 5.0^(@)C cm^(-1) at cross section A and is 2.5^(@)Ccm^(-1) at cross section B. calculate the rate at which the temperature is increasing in the part AB of the rod. The heat capacity of the part AB =0.40J^(@)C^(-1) , thermal conductivity of the material of the rod. K=200Wm^(-1)C^(-1) . Neglect any loss of heat to the atmosphere.
